1,278,617. Original application filed August 2, 1915,

gether with the accompanying drawings, is a specificatiom'the present application be ing a division of my copending application SerialNo. 43,132, filed August 2, 1915.

The present invention relates to a rolling mill and has particular reference to a con struction employed for directing cooling water against the operating surfaces of the rolls of such a mill. The invention is here shown in connection with a construction embodying two stands of reducing rolls dis-' posed in a single housing, the said construction being applicable to the method of rolling rounds fully set forth and described in my Letters Patent of the United States No. 1,193,001, granted August 1, 1916; but it is to be understood that my invention is applicable to any and all types of reducing rolls and is not confined inan sense to employment with rolls disposed in stands My invention is fully set forth in the following description, reference. being had to the accompanying drawings, in which- Figure 1 is a side elevation, partially in vertical section, of the roll housing to which my invention is here shown as applied, and

Fig. 2 is a horizontal sectional view thereof on the line 2-2, Fig. 1.

Similar reference characters refer to similar parts in both. figures.

Referring to the drawings, as showing a mechanism of the type set forth and described in my aforesaid copending application, 1 indicates a pinion housing which serves for the support of a roll housing 2, the latter carrying both the vertical and the horizontal stands of rolls above referred to. The said roll housing, for convenience of description, may be considered as being divided roughly by a transverse wall 3 into two compartments, one, 4, containing the stand of vertical rolls 5, 5, and the other,

6, containing the stand of horizontal rolls,'7, 7 The compartment 4 is defined by side walls 8, 8, oined together at the top and bottom by transverse upper and lower front walls 9, 10, which have a rectangular opening. 11 between them. The compartment 4 thereby presents separated upper and lower sub-- stantially inolosed recesses, which are designed to contain respectively the upper and lower pairs of bearings 12, 12 and 13, 13 for the necks of the vertical rolls 5, 5.

The compartment 6 of the roll housing 2, containing the pair of horizontal rolls 7, 7, is defined roughly by a pair of spacedupright walls 14, disposed parallel to and at a distance from the partition 3. In the recesses thus formed at each side of the housing, the bearings 15, 15 and 16, 16 for the necks of rolls 7 are received. In the rectangular opening 11, between the front walls 9, 10 of the housing, is supported a fixed receiving guide 17 for the metal, said guide projecting inwardly into juxtaposition with the pass of the vertical rolls 5, 5. The partitio'n 3 supports a'fixed intermediate guide '18 adapted to convey the metal from the pass of the vertical rolls to the pass of the horizontal rolls 7. These two guides are in axial alinement with each other, and also with a third fixed delivery guide 19, supported by a plate 20 which is attached to the rear Walls 14 which inclose the bearings 15 and 16 of the horizontal rolls. The longitudinal or axial adjustment of the rolls, each of .which has the usual series of peripheral grooves cotiperating to form passes of various sizes, will now be described, it

being understood that the said adjustment is effective not only in bringing a pass into proper alinement with the fixed guides 17 18 and 19, but also in renderingpossible the substitution of various passes, without removal of the rolls from their bearings and without disconnecting the driving shafts of said rolls from the shafts of the driving pinions. Since the axial adjustment devices for all the rolls of the two stands of rolls are identical, a descri tion of the same with respect to the vertica rolls will sufiioe for the horizontal rolls.

7 ing. The free end of each upper yoke 22 is BEST AVAILABLE COP The walls of housing 2 provide, adjacent the outer end of each roll bearing 12, 13 15- within said notches to'afi'ord the-fulcrums for 7 each yoke. The inner face of each yoke provides raised projections 25 adapted to bear against the outer end of the adjacent bearslotted for the passage of a fixed rod 26, carried by the housing,- on the upper end of which a washer 27 is pressed against the yoke 22 by adjusting nuts 28; The. downward movement of said nuts rocks the yoke downwardly, Fig. 1, to carry the upper bearing 12 in the same direction. Each lower yoke 23 has connected thereto a slid-- ingrod 29, by means of pins 30, which limit relative movement between rod and yoke. The upper end of said rod 29, projecting beyond the housing, carrie adjusting nuts 31, by means of which the inward movement of the lower bearing 13 is secured. The adjusting devices of the two bearings arethus located conveniently at one end of p the roll, and the inward adjustment of each bearing is made dependent upon the amount by which the adj ustment of the device of the other bearing is loosened, that is, when a roll 5 is to be ad usted downward, the retaining rod for its lower yoke23 is loosened an appropriate amount, and then" the upper yoke 22 is drawn downwardly a corresponding amount, both of these adjustments being performed at the top'of the housing. The

yokes 22 for the two bearings of each horizontal roll have the same adjustment devices as described above.

Referring to Fig. 1, the vertical roll 5 shown therein provides, in the present instance, four peripheral grooves 32, 33, 34

and35, the roll being so disposed axially as to bring the groove 34 into approximate alinement with the guide 17 18 and 19. In'

order to secure a delicate adjustment, the two yokes 22 and 23 are moved in or out by the adjusting nuts 28 and 31. In order to bring the groove 35 into the same position as the groove 34, the yokes 22 and 23 are elevated to bring their ears 24 into the notches 21, just above those in which they are shown as located in Fig. 1. In the same manner, each of the two other grooves 32 and 33 may be rendered available by removing the roll with its bearings 12 and 13 and replacing thesame in a reversed position. It will be clearly-understood that each roll of both stands of rolls is longitudinally adjustable in recisely the same manner as above ,descri ed, in order not only to render the different grooves of the same available to form the pass, but also to afford a delicate and accurate alinement of each groove with the guides 17, Band 19.

The adjustment and reversal of the rolls above described is permitted by reason ofthe novel driving means providedtherefor, which is in all essential respects the same for each roll and hence it will ,be suffi'cient to describe it in detail for one of the vertical rolls shown in Fi 1. A pinion 36 is driven from a shaft 3 the latter being operatively connected to a source of power, not shown. The pinion36 providesa square opening for the reception of a square end 38of a shaft 39, which projects through the yoke 23 and enters the roll 5. The said roll is bored out from end to end and then squared, so that the square upper end 40 of shaft 39 is'capableof imparting rotation to the roll in all positions of ad ustment assumed by said roll. As shown in Figs. 1 and 2, the square openings in the roll and in. the pinion 36 are sli htly larger thanthe squared, ends of the s aft 39, so that sufiicient play necessary for any sli ht lateral adjustments of the roll is aiforde The devices employed for efl'ectin such lateral adjustments form no part -0 the present invention, and hence are not described in detail herein, the same being fully set forth in my aforesaid copending application Serial No. 43,132. The novel drivin the rolls, as above described, w ich are also employed in connection with the horizontal rolls 7, 7, are likewise made the subject of a separate copending application Serial No. 130,493, filed November 9,1916.

means. for

Each roll is partially surrounded by a water nozzle 41, providmga series-of er-- forations for direct streams of water agalnst the operating surface of the roll. The nozzle 41 for the vertical rolls 5 are shown in Fig. 2, thesamebeing fixed to the walls of the housing or secured in any suitable manner in the positions shown; the nozzles for the horizontal rolls 7 are not shown. In order to prevent the water discharged by said nozzles upon the vertical rolls from passing into the pinion housing 1, each lower adjusting yoke 23 has a depending skirt 42, surrounding a restricted neck 43 of a water guard 44, through which passes the shaft 39 of the roll. The waterguard flares outwardly at the bottom, as shown at 45, in

surrounding relation to the bearing for the upper end of pinion 36, so that the descending water is directed away from the interior of the pinion housing.
